Answer:
7 books
Step-by-step explanation:
you need to divide the books by the piles so 28 divided by 4 which equals 7
Since there are 4 piles and 28 books, let's draw a diagram.
So we have 28 books.
Let each line represent the separation of the books.
║║║
║║║
Each pile has 7 books, and if you count them, there'll be EXACTLY 28 books.
Hope this helps
